Level 517 is the second level in Sour Salon and the 89th mixed mode level (63rd jelly-order). To pass this level, you must clear 38 single, 41 double jelly squares, collect 25 chocolate squares and 40 candy bombs in 24 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
The double jellies are under the chocolate and sugar chests. The single jellies occupy every other space.
Candy bombs are in the sugar chests, and they have 20 moves before exploding.
A sugar key spawns every move, which means that the initial candy bombs can be defused in time, before more will spawn from their candy cannons. However, they pose no threat after four moves has elapsed, and the last one spawns at 19 moves left.
The chocolate and five colours make it slightly harder to reach the bombs.
